Which factor is not considered in ventilation systems?

In the context of ventilation systems, the primary goal is to maintain a healthy and comfortable indoor environment, and several factors are typically considered in this process. Among those factors, humidity control plays a significant role as it directly affects both air quality and comfort levels within a space.

While fresh air circulation, temperature control, and air quality improvement are crucial components of a proper ventilation system, humidity control is often seen as a result of these systems rather than a primary factor. Proper ventilation can help manage humidity levels by bringing in fresh air that may have lower humidity and by exhausting moist air. However, the primary aim of ventilation systems is often to ensure adequate air flow, improve air quality, and maintain temperature rather than directly control humidity.

Therefore, the selection of humidity control as a factor not considered in ventilation systems emphasizes that while humidity management is important, it is typically regarded as an outcome of effective ventilation rather than a direct criterion in ventilation system design or operation.
